nlecomposition: Always execute seeks

Browse source 
We have an optiominisation to avoid double seeks when a seek is passed
the end of the current stack. The problem, is that we no longer flush
the pipeline when this code is reached. This patch comments out this
optimization adding a FIXME. As mention, flushing the stack instead of
seeking would work, but does not seem trivial considering all the
mechanic inplace to forward or not the events.
